Vaporizer cartridge for a vaporizer

Abstract

Features relating to a cartridge for use with a vaporizer body are provided. The cartridge mates with the vaporizer body in a cartridge receptacle. The cartridge may include a cartridge body defining a reservoir configured to contain vaporizable material; a mouthpiece coupled to a proximal end region of the cartridge body; at least one proximal absorbent pad wedged within an internal volume of the mouthpiece; a mouthpiece seal with sealing ribs; a cannula defining a vaporization chamber extending through the cartridge body; a resistive heating element; a porous wick configured to draw the vaporizable material in the reservoir towards the vaporization chamber; an internal sealing gasket positioned in a distal end region of the cartridge body; a lower support structure positioned in the distal end region of the cartridge body; and at least one distal absorbent pad configured to wedge within a recess located in the lower support structure.

What is claimed is: 
     
       1. A cartridge configured to operatively couple with a vaporizer, the cartridge comprising:
 a cartridge body defining, at least in part, a reservoir configured to contain vaporizable material; 
 a vaporizing assembly positioned within the cartridge body in fluid communication with the reservoir, the vaporizing assembly configured to vaporize the vaporizable material; 
 a mouthpiece coupled to a proximal end region of the cartridge body, the mouthpiece comprising an internal volume and an external surface defining at least one opening into the internal volume; and 
 at least one absorbent pad wedged within the internal volume of the mouthpiece; 
 wherein a central, upper element defines in part a top surface of the cartridge body, wherein the central upper element extends across a major axis of the cartridge body between sidewalls of the cartridge body and comprises a side cross-sectional profile having a sharpened end that is configured to split vapor flow around the central, upper element and to the mouthpiece such that particles within the vapor flow are entrained in the at least one absorbent pad. 
 
     
     
       2. The cartridge of  claim 1 , wherein the at least one absorbent pad comprises a pair of absorbent pads wedged within the internal volume of the mouthpiece, wherein the pair of absorbent pads are oriented opposite with respect to one another and at an angle with respect to the direction of vapor flow through the mouthpiece, and further wherein the central upper element is positioned between the pair of absorbent pads. 
     
     
       3. The cartridge of  claim 2 , wherein the at least one opening in the mouthpiece is a narrow, elongate slit, and wherein an opening between the pair of absorbent pads corresponds to a shape of the slit. 
     
     
       4. The cartridge of  claim 2 , wherein the pair of absorbent pads engage with an interior flange of the mouthpiece. 
     
     
       5. The cartridge of  claim 4 , wherein the interior flange of the mouthpiece orients the pair of absorbent pads at an angle with respect to a vertical axis of the cartridge. 
     
     
       6. The cartridge of  claim 1 , wherein the at least one absorbent pad comprises one absorbent pad surrounding the at least one opening of the mouthpiece;
 wherein the at least one opening in the mouthpiece is a narrow, elongate slit and the one absorbent pad is a flattened disk defining a central opening; 
 wherein the central opening has a shape that corresponds to a shape of the slit. 
 
     
     
       7. The cartridge of  claim 6 , wherein the one absorbent pad is wedged within the internal volume of the mouthpiece to avoid blocking gas flow through the at least one opening. 
     
     
       8. The cartridge of  claim 6 , wherein the one absorbent pad has an outer perimeter wall sized and shaped to engage with an inner wall of the mouthpiece. 
     
     
       9. A cartridge configured to operatively couple with a vaporizer, the cartridge comprising:
 a cartridge body defining, at least in part, a reservoir configured to contain vaporizable material; 
 a vaporizing assembly positioned within the cartridge body in fluid communication with the reservoir, the vaporizing assembly configured to vaporize the vaporizable material; 
 a mouthpiece coupled to a proximal end region of the cartridge body, the mouthpiece comprising at least one opening configured to release vapor from the vaporizing assembly; and 
 a mouthpiece seal positioned between an inner surface of the mouthpiece and an outer surface of the cartridge body.
